APPARATUS FOIL FORMING RINGS OB BEADS ON THE NECKS OF TOY BALLOONS.

Application med To all whom it may concern;

Be it known that L'NELT BARR, a citizen of the United States, residin'at Lorain, in the county of Lorain and tate of Ohio, have invented acertain new and useful Improvement in Apparatus for Forming Rings orBeads on the Necks of Toy Balloons, of which'the following is a full,clear, and exact description.

This invention relates to a method and beads on the for its object toreduce the time and therefore the cost of rolling up the rubber on theneck POIgIlOIS ea s balloons after the forms into the rubber solution,the rubber surrounding the necks of the forms is rolled for a distancealong the necks to form thick ened portions in the form of beads orrings at the ends of the necks of the. balloons.

Heretofore this has been done by hand, an operator with her fingersrolling up the rubber on the neck of eachform' and consequently thishand operation adds measurably to the cost of the balloons. By myinvention the rolling up operation is performed mechanically andquickly. Preferably this is accomplished by bringing the forms intocontact with one or more revolving rolled up by a brushing The inventionmay be marized as consisting in certain novel action. further brieflysumtails of construction and combinations and arrangements of parts andin the steps of the improved method which will be described in thespecification and set forth in the appended claims.

. In t e accompanying Fig. 1 is a top plan view of the apparatus; Fig. 2is an end view; Fig. 3 is a side view with parts in sectionsubstantially alon the line 3-3 of Fig. 2; Fig. 4: shows mo ifiedballoon forms and Fig. 5 shows modified brushes which are preferablyused therewith; Fig. 6 is an enlarged view illustratin the rollingaction of the r11 ber of: the neck of the form.

In carrying out my invention, the rubber is rolled up the necks of theforms b 1 a brushing action, and this is done pref erably by moving aseries of forms between sheet of drawings,

beneath the shafts 14 that brushes so that the rubber will be brushes onthe Serial 1T0. 494,741.

a pair of oppositely rotating brushes. apparatus used in carrying outthis method preferably includes a horizontal table 10 having two longupright strips 11 adjustable toward and from each other by adjustingscrews 12 and carrying brackets 13 in which are journaled long shafts 14provided with closely arranged oppositely disposed rotary brushes 15 andwith pulleys 16 adapted to be engaged by motor driven belts so as todrive the brushes 15 in opposite directions. By adjusting the strips 11toward and from each other the distance between the brushes can be madeanything that is desired, as is obvious from Figs. 1 and 2. The distancebetween the brushes 1? and pulley 16 is such that a strip or serles ofwithout striking the pulleys.

T he forms on which the balloons are made are in Figs. 1, 2 and 3, shownat 17, which forms are carried by and arranged at right angles to astrip or base 18. These forms are designed to be run between therotatingbrushes 15 and to facilitate this I provide drive the brushes a guide 19in the form of a strip having spaced guide ribs 20, this strip 19 beingin this instance hinged at its end remote from the brushes as shown at21, to the top of the table, and

at its opposite end bein adjustably supported a ing screw 22. Thisadjusting screw is ust beneath.the brushes so that the relative heightto the brushes and forms can be adjusted at the point where the formspass between the brushes.

In Fig. 4 I have shown elongated forms 17 for forming what is known as asausage-shaped balloon, and with these forms I prefer to use beveledbrushes 15 as shown in Fig. 15, whereas the brushes shown in Fi 1 arecylindrical brushes, which are preferably provided side by side so thatthe rubber will be properly rolled up the neck in the event the firstpair of brushes do not accomplish this work.

' In operation case may be, are adjusted as one another and the. guidestrip 19 is adjusted as to height to adapt the apparatus for forms of agiven size, then the operator standing at one end of the table insertsthe brushes 15 or 15 as the a series of to spacing from by means of an ajusta g g I neiaore them inwardly until all the forms have separatelypassed between the brushes, and then the operator ulls the Thus by aquick inwardand outward stroke of the forms the rubber is rolled upwardalong the necks of the forms so as to form the rings or beads of theright diameter on the ends of the necks of the balloons, and

' this is donejust as effectively but in far less time than is requiredby the hand rolling operation.

I do not desire to be confined to the precise details shown or theprecise steps of the 'method, but a1m in my claims to cover allmodifications which do not involve any departure from the spirit andscope of my invention.

Having described my invention, ll claim:

1. ii an apparatus forforming beads or rings on the ends of the necks oftoy balloons, a table having a pair of oppositely disposed brushes,means for rotating the brushes in opposite directions, means forsupporting the brushes so that they may be ad usted toward and from eachother, guide means for a member carrying alongitudinal' row of balloonforms, said guide means extending lengthwise of the table so that theballoon forms may be caused to pass in suceession between the brushes,and means for adjusting the guide means so that the pentions of theballoon forms passing between the brushes may be raised and lowered.

2. In an apparatus for forming beads or forms outwardly.
